Ice-cream freezer



Feb. 24, 1931. M. A. ROLLMAN ICE CREAM FREEZER Filed July 16, 1929 Patented Feb. 24, 1931 MICHAEL A. ROLLMAN, OF MOUNT JOY, PENNSYLVANIA ICE-CREAM FREEZER Application filed July 16,

The object of this invention is to provide a simple device for removably locking the gearing-bridge to the tube, as more fully hereinafter set forth.

Referring to the drawing annexed Fig. 1 is a perspective view of an ice cream freezer provided with my invention;

Fig. 2 is a vertical sectional view thereof;

Fig. 3 is a plan View showing part of the bucket in horizontal section;

Fig. 4c is a view showing the device applied to a wooden bucket.

Referring to Figs. 1, 2 and 3, 5 designates a metal ice-bucket; 6, the cream-can; and 7, the usual gearingbridge plate carrying the usual gearing for operating the dasher and can and embodying a hand-operated crank-shaft 8 journalled in upstanding brackets 9 mounted on the bridge-plate 7. This bridge-plate 7 is adapted to be attached to the can in the usual manner, namely, by tongues 10 at one end, which tongues are adapted to be inserted in holes in the metal bucket,.and by means of alip 11 formed at the other end of the bridge plate, this lip 11 being adapted to engage over the usual keeper 12 formed on the bucketbody.

To look the bridge-plate removably in place on the can, I employ a slidable wire lockingdevice consisting of a pair of spring-arms 13 adapted to lie on the top-face of the plate 7 and connected at their inner ends by an upstanding loop 14: which embraces the shaft 8 and is slidable therealong. The arms 13 tend to spring inwardly so as to normally engage in notches 15 formed in the edges of the outer bearing 9. The free ends of the spring wire 13 curve slightly inwardly toward each other and, when the Wire frame is pushed radially outwardly toward the handle of the shaft 8, these free ends pass through a circumferential slot 16 formed in the bucket-body and engage the opposite ends of said slot, this engagement being such as to bend the free ends of the arms 13 inwardly toward each other sufficiently to clamp the wire arms 13 firmly in their notches 15, to

1 thus frictionally hold the wire locking-frame in locked position. When the bridge-plate is put into place, the Wire locking-frame is 1929. Serial 1%. 378,648.

slid inwardly to the position shown in Fig. 3, and then the bridge-plate may be locked to the bucket by sliding the wire frame radially outwardly to thus cause the free ends of the arms 13 to spring inwardly and clamp against the outer bracket 9, thereby firmly locking the bridge-plate in place and yet permitting it to be readily disconnected from the freezer by sliding the wire frame inwardly again.

The same construction is shown in Fig. 4 except that, in view of the fact that the bucket is made of wood staves, it is necessary to fasten to the bucket upstanding metal plates 17 for engagement with the bridge" plate 7, these plates 17 forming virtually parts of the body of thebucket.

Vhat I claim as new is:

1. In combination with a bucket, a gear- 1ng-bridge carrying an upstanding bracket and a horizontal shaft, a spring wire lockingdevice bent midway its length to overhang said shaft and having a pair of resilient arms extending radially outwardly with respect to the bucket and lying in notches in the aforesaid upstanding bracket, said bucket being provided with an opening adapted when said wire locking-device is slid outwardly to force said arms in said notches.

2. The combination with a bucket lli-lflllg removable gearing-bridge plate carrying an upstanding bracket in which the operating shaft is journalled, of a locking-device in the form of a sliding frame provided with a pair of springarms normally hugging said bearing-bracket and having inwardly-hent "free ends extending beyoml said li racket and adapted to engage an opening in. the bucket, for the purpose set'fortlrl.

3. In combination with a bucket having a removable gearing-bridge plate carrying a shaft and an upstanding bearing member therefor having notches in its opposite edges, said member being arranged transversely of the gearing-bridge plate, a sliding lockingframe in guiding relation with said shaft and having a pair of spring-arms lying on the plate and adapted to spring into said notches, the free ends of these arms being 6)? tended beyond said member and bent to what...

7 removable gearing-bridge plate carrying a ward each other and the bucket being provided with an opening through which said arms extend when the frame is slid outward- 1y into locking position. i

4. In combination With a bucket having a shaft and an upstanding bearing member therefor having notches in its opposite edges, 7

said member being arranged transversely of the gearing-bridge plate, a sliding locking-frame having a pair of spring-arms lyingon the plate-and adapted to spring into said notches, the free ends ofthese arms being extended beyond said member and bent toward each other and the bucket being provided with an opening through which said arms extend when the frame is slid outwardly into locking position.

In testimony whereof I hereunto affix my signature.
